JASON-1/-2, TOPEX, ERS-2, ENVISAT and GFO Sea Height Anomaly (SHA) and Significant Wave Height data are available here on a near-real time basis with a 2-day average delay. These data have been processed by the NRL site at the Stennis Space Center. The maps shown here are generated by interpolating SHA data corresponding to a 10-day period
ending on the selected date.
As an additional product, geostrophic currents are also estimated using the SHA values and a climatological mean dynamic height field.
